CHECKING THE MAXIMUM OPERATING FREQUENCY (MAX FREQ - default 50 Hz)
Verify that the parameter MAX FREQ match the frequency of the motor plate (default 50 Hz)
IMPORTANT: the choice of exceeding the maximum frequency is the responsibility of the installer,
who must realise the consequences of raising the maximum frequency on the risks related to the
motor, to the pump and to the electrical system.

SETTING THE OFF FREQUENCY (OFF FREQ. SP1) (operation without flow sensor)
Verify that the parameter OFF FREQ. SP1 (shutdown frequency) matches the frequency of minimum flow (flow
off).
IMPORTANT: If the OFF FREQUENCY setting is too high, this will cause the pump to stop while the
request is still active, and involve frequent restarts; if the setting is too low, this could cause the
continuous operation of the pump even at zero flow, with pump overheating and damage.
For more details on this parameter see part 2 of the manual (PART 2 - USER'S MANUAL)
